Dan Farina 309bb92d95 Prevent a double-free ...

This can occur because prior to this, there is a code path that looks
like this:

    primaryConn = myLocalConn

CloseConnections will subsequently try to free both with PQFinish.
I'm not sure if this is the right fix -- it's more of hack -- without
more information about design intention.

One reasonable alternative would be to have CloseConnections perform
this check itself. As-is I am pretty sure that this fix leaves a
signal-race (when CloseConnections is called, without the check, in
the interrupt handler) unfixed.
